Currently we carry only genuine Rainbow vacuum water pans. They are very well glued together and much less brittle than aftermarket parts that we know. The most popular are regula 2 quart size containers but if you have a large house or are fairly often using your Rainbow for shampooing carpets or picking up water - go for the larger 4 quart option. This will save you time as you will not need to dump the water as often as with the regular size container.

Keep in mind that larger container will lift the vacuum a little bit
higher and it will make it easier to tip over your Rainbow. Since
e-series container is not as tall as D3-Se water pan it is less prone
to tipping over. However if you are D3; D4 or SE rainbow model owner -
be carefull with the tall container. if you choose to pull your vacuum
by the hose - do it carefully.
Bad news for D2 (metal Rainbow vacuum) owners. A while ago manufacturer
discontinued manufacturing and selling water containers for those
models. They are a bit different from newer ones so D3/D4/SE part will
not fit your D4.
